Product note
Kabeldon cable termination for GIS and TRF, 420 kV
APEGA 420
Cable termination suitable as a fixed
connection point in a gas-insulated
switchgear, a transformer without
a separate cable box or where the
cable box is filled with transformer oil.
Designed to meet the requirements of
internationally accepted standards.
